Answer:
Bird flu illness in people has ranged from mild to severe. Signs and symptoms of bird flu infections in people can include fever (temperature of 100ºF [37.8ºC] or greater) or feel feverish, cough, sore throat, runny or stuffy nose, muscle or body aches, fatigue, headaches, eye redness (or conjunctivitis), and difficulty breathing. Other possible symptoms are diarrhea, nausea, and vomiting. As with seasonal flu, some people are at high risk of getting very sick from bird flu infections, including pregnant women, people with weakened immune systems and people 65 and older. Human infections with bird flu viruses usually can be treated with the same prescription drugs that are used to treat human seasonal flu viruses. These are called “flu antiviral drugs.”
